RING SPINNING AND TWIS'IING- APPARATUS.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed April 5, 1907. Serial No. 366,468.

To all whom it may concern:

Be it known that I, THOMAS C. POWELL, a citizen of the United States of America, and

a resident of Boston, in the county of Suffolk upon a suitable plate or holder provided with clips engaging shoulders upon said intermediate member to permit a certain amount of horizontal or vertical movement, at the same time preventing its rotation.

Another object of the invention is to reduce the friction between the supporting plate and the intermediate member by providing the latter with a depressed annular rib, the lower edge of which alone contacts with the supporting plate.

The invention has for its further object a provision whereby the intermediate member and the supporting plate may be centered when the device is being installed upon the spinning frame.

The invention consists further in-certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings: Figure 1 represents a plan of a spinning ring and its holder, shown in position upon a ring rail with the intermediate member centered with the supporting plate by means of suitable centering pins. Fig. 2 represents a section on line 2-2 on Fig. 1. Fig. 3 represents a plan of the spinning ring applied to the ring rail, similar to Fig. 1, with the centering pins removed to permit a certain longitudinal movement of the intermediate member upon the supporting plate. Fig. 1 represents a vertical section of the same on line 4-4 on Fig. 3. Fig. 5 represents a vertical section of the same on line 5-5 on Fig. 3. 'Fig. 6 represents a perspective view of a forkedhandle centering device. Fig. 7 represents an inverted plan of the supporting plate or holder. Fig. 8 represents an inverted plan of the intermediate member. Fig. 9 represents a sectional detail of a portion of the supporting plate and the intermediate member, and Figs. 10 and 11 represent details in plan of a portion of the intermediate member showing modified forms of the holes extending through the same by which said membpr may be centered with the supporting p ate.

Similar characters designate like parts throughout the several figures of the drawmgs.

In the drawings, 10 represents the ordinary ring rail to which is secured by means of screws 11 a ring supporting plate or holder 12. The plate 12 is provided with a plurality of upwardly extending clips 13 having inwardly bent lips 14 which project inwardly above the intermediate member 15. This intermediate member is made flat so that it may be readily punched out and is provided with a plurality of notches 16 in its edge, said notches 16 corresponding in number to the clips 13 extending upwardly from the plate or holder 12. The notches 16 are made somewhat wider than the width of the clips 13 so that the intermediate member may be moved to a limited extent around the axis thereof. The depthof the notches 16 is such as to allow a certain amount of lateral movement to the intermediate member. This makes a convenient construction of a rin supporter which is adapted to have a limited degree of horizontal or vertical movement while its rotation is prevented.

When spinning rings are being installed upon. the ring rail where an intermediate member is used between the supporting plate and the ring it is almost impossible under ordinaryconditions to center the supporting plate when the movable intermediate member has been previously secured thereto which is necessary owing to the construction of the device. It is, however, quite essential in order to secure the proper working of the spinning ring to have the ring supporting member centered with the spindle or axis of the cop on which the thread or yarn is being wound. In order to secure this desirable result the intermediate member is provided with a pair of holes 17 extending therethrough while the supporting plate is provided with a corresponding pair of holes or openings 18 extending therethrough, the location of the holes or openings 17 and 18 being equidistant from the center of the intermediate member 15 and the supporting plate 12.

A forked tool 19 provided with a handle 20 is provided having suitable ends 21 which nicely fit the openings 17 and 18. W hen the ends 21 are inserted in these openings 17 and 18 the two members 12 and 15 are held together perfectly centered and may be readily moved about upon the ring rail to center the Whole device with the ring 22 held in position upon the intermediate member 15 by means of a plurality of clips 23. The whole device is retained with the plates thereof locked one to the other by means of the forked tool 19 until the plate 12 has been secured to the ring rail by the screws 11. When the tool 19 is removed the intermediate member 15 with its spinning ring locked thereto is free to move horizontally over the upper surface of the supporting plate 12 to center the ring with the cop or bobbin being Wound when any inequalities occur therein. At the same time the intermediate member 15 with the ring attached thereto is permitted slight vertical movement when such movement is necessary for the proper operation of the device. Instead of the forked tool 19 being used, pins 24 such as are shown in Figs. 1 and 2 may be used to accomplish the same object, these pins being removed as soon as the supporting plate 12 has been socured to the ring rail 10 by means of the screws 11 after which the limited horizontal and vertical movement desired may be ob tained.

In order to reduce to a minimum the friction between the intermediate member 15 and the supporting plate 12 when moving one upon the other, a rib such as 25 is interposed between the two thus greatly reducing the frictional contact between. the two members. In the drawings this rib is shown as a depression formed in the intermediate member 15 and extending downwardly from its lower face the lower edge of which contacts with the upper face of the supporting plate 12 over which it moves.

In order to further facilitate the centering of the intermediate member 15 with the supporting plate 12 the central opening through the intermediate member is made somewhat larger than the central opening through the plate 12 so that in looking down upon the two in plan the two plates or members may be more readily centered. in an obvious manner, it being perfectly evident that when an equal amount of surface of the lower plate shows beyond the inner edge of the upper plate or intermediate member the two members must necessarily be centered.

The holes 17 through the intermediate member may be round holes fitting the pins 24 or the ends 21 of the forked tool 19, or

they may be slots cut into the member from the outer edge, as in Fig. 10, or from the inner edge, as in Fig. 11, without affecting the principles of the invention. The pins 24 may be threaded as shown in the drawings these threaded ends engaging with the threads of the holes 18 in the lower plate tomore securely lock the two members 12 and 15 together.

- The advantages of such a device to be used in the installation of spinning rings upon the spinning frame is so apparent and the operation is so evident that it is not deemed necessary for any further description.

Having thus described my invention, I claim:

1. The combination with a spinning ring, of a supporting plate or holder; an intermediate member secured to said ring and movable upon said plate or holder; means for holding together said plate and intermediate member; and means for securing said plate or holder to the ring rail said intermediate member and plate being provided with means for centering them.

'2. The combination with a spinning ring of a supporting plate or holder provided with a pair of holes extending through said plate; an intermediate member secured to said ring and movable upon said plate provided with a corresponding pair of holes; means for holding together said plate and intermediate member; means for securing said plate or holder to the ring rail.

3. The combination with a spinning ring, of a supporting member consisting of a plate; a flat intermediate member secured to said ring and movable upon said plate provided and intermediate member; means for securing said plate rigidly to the ring rail; and means for limiting the movement of said intermediate member relative to said plate in either direction.

4. The combination with a spinning ring, of a supporting member consisting of a plate; a flat intermediate member secured to said ring and movable upon said plate; a rib upon one of said members and contacting with the adjacent face of the other member; means for holding together said plate and intermediate member; means for securing said plate rigidly to the ring rail; and means for limiting the movement of said intermediate member relative to said plate in either direction.

Signed by me at Boston, Mass, this 27th day of March, 1907.
